5 Reasons to Train with a Power Meter

All other things being equal, the more power you can produce, the faster you can ride a bicycle over a given distance. That's why increasing cycling power is so important for competitive cyclists and triathletes.

While there are other steps you can take to help boost power, here are five reasons you should be training with a power meter.

#1. Access to Significant Information

A power meter provides you with extensive information about every ride you take. This includes basic information such as distance, cadence and miles per hour. It also includes more sophisticated data such as average power for various segments of the ride (measured in watts), time spent in your power-based training zones, time spent at various cadences, the relative intensity of the ride and total work performed (measured in kilojoules).

You can use this information to better understand your strengths and weaknesses as an athlete, and to develop training specifically designed to enhance those weaknesses.

# 2. Accurate Goal Measurement

Training with a power meter makes it easier to determine if you have achieved your goals for a workout, race, mesocycle, race season or calendar year.

For example, if you are performing a series of 10-minute intervals and your goal is to maintain an average power of 250 watts, it will be clear whether you have achieved this goal. No matter the conditions or terrain, you have either maintained an average power of 250 watts for each interval or you have not. There is no ambiguity.

Likewise, if you want to compare your training load from one mesocycle to the next, you can review your Training Stress Score (a composite number that uses the duration and intensity of each ride to arrive at an estimate of overall training load) for each mesocycle to clearly determine the amount of work you are performing for a given time period. Once again, there is no ambiguity.

That is the beauty of training and racing with a power meter. You get consistent, accurate data from one workout to the next.

#3. True Rate of Work

A power meter gives you an accurate and consistent indication of your rate of work (power production), unlike other measures such as heart rate which can be affected by many variables that have little to do with actual work rate such as hydration, air temperature and stress level.

For example, if you ride for one hour and your average power is 275 watts, you can be sure this is an accurate indication of your work rate on the bike. The conditions don't matter. The actual power you produce is the same as any other one hour ride resulting in an average power of 275 watts.
